i wouldn't buy too much right now. the price has been going down for a while, but honestly i believe this isn't something that's going to go away any time soon. if you have the money to, then i'd invest it. it can be a crazy market, but in the looong run there will definitely be a return.
i'm in that same boat too lol; my father and i have been watching bitcoin for just over a year. one day my dad came home asking me all about it after a conversation with his coworkers and he decided he wanted in.
